The selected Calculated Carbon Parameter has been dismissed in October 2017! Legacy values will be exported as is and displayed in red with subscript "c", e.g. -0.123456_c! No data available? Insert -999 No suggestion for adjustment possible? Insert -888 To calibrate CTDsal use: CTDsal_calibrated = (CTDsal - CTDsal_intercept) / CTDsal_slope To calibrate CTDoxy use: CTDoxy_calibrated = (CTDoxy - CTDoxy_intercept) / CTDoxy_slope

09AR19960119 - cfc11

Measured at a time of still changing CFCs in the atmosphere so the observed
undersaturation is as expected.

Posted by siv.lauvset@uib.no on 2018-10-01 10:26:04 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

09AR19960119 - cfc12

Measured at a time of still changing CFCs in the atmosphere so the observed
undersaturation is as expected.

Posted by siv.lauvset@uib.no on 2018-10-01 10:25:57 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

09AR19960119 - cfc12

See comment CFC_11.

Posted by nlange@geomar.de on 2018-05-07 14:38:48 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

09AR19960119 - cfc11

Both tracer data seem to have an offset, hence the good fit between them might
be deceptive; Almost all profiles show saturation ratios below 1 and many of
them below 0.95.
This might have a natural cause - water mass formation (Rhein et al. 2002)...
Further there is no crossover cruises from that year for comparison, but AR1996
shows higher values than cruises from 1994.

Posted by nlange@geomar.de on 2018-05-07 14:37:37 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

09AR19960119 - silicate

Good agreement between all crossovers indicate too low concentrations. All
offsets are clearly below the limit of 0.98. Following the mean weighted offset
of 0.92 apply adjustment of 1.08.

Posted by nlange@geomar.de on 2018-05-07 14:34:22 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

09AR19960119 - phosphate

Most crossovers show offsets less than 1%. All offsets within acceptable range.
No adjustment needed.

Posted by nlange@geomar.de on 2018-05-07 14:32:07 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

09AR19960119 - salinity

Crossovers show large variability - offsets above and below 1 exist. If standard
deviations of individual offsets included, most crossovers lie in acceptable
range. Maintain 0.00.

Posted by nlange@geomar.de on 2018-05-07 14:30:17 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

09AR19960119 - oxygen

The majority of crossovers shows offsets within the acceptable range. Only 3
offsets above 1, all other indicate too low oxygen concentrations - the mean
equals 0.994. However, not enough evidence to submit such a small adjustment.
